Jetbot not able to connect to network

You should definitely try reaching out to Nvidia support since they wrote the OS image. Reference this forum thread and offer as much info as possible

I suspect the issue could be with the router. I had a hell of time getting a stable connection with the n150 edimax when i tried at home on my tp-link wr841n router. Interestingly, the connection was very stable with low latency response when i took it to work. I dont know the exact router in the office, but it works anytime i take it to office but gets unstable at home. I will update on the office router type.

I just received the SparkFun JetBot Nano kit and have been having very similar issues.

Like the poster here, I also thought this was due to a faulty WiFi adapter.

But now, I think that this behavior is related to power management on the Linux side. I ran across this post https://askubuntu.com/a/707132. And there is a linked post here: https://www.raspberrypi.org/forums/view … hp?t=61665. Although these are technically for a different version of the WiFi adapter, I think the premise is the same.

Running lsmod I surmised the controller/driver name is ‘8732bu’.

So on the device, I created a file:

/etc/modprobe.d/8732bu.conf

and added the contents:


options 8732bu rtw_power_mgnt=0 rtw_enusbss=0

I also ran this on the device but I’m not sure this helped sudo iw dev wlan0 set power_save off.

Then I rebooted and turned WiFi on and off in the Ubuntu UI. Then I was finally able to play with the Jetbot Nano!

Before this, the Jetbot would disconnect from the WiFi after a few seconds. Then it would be pretty tough to get the WiFi back connected. I think just turning off and turning the WiFi back on seems to work now. I’m doing this on the Ubuntu UI.

I ran into this link https://www.digikey.com/en/maker/projec … 81b80b8ec2 which mentions that you can update a /etc/modeprobe.d/blacklist.conf which might give similar results.

So it’s a bit clunky getting it to connect to WiFi but hopefully this will help someone get the WiFi connected. Also, I did realize that the IP address / or No Internet Connection that shows on OLED is not always accurate. There can be no internet connection when the LED shows internet connection; also I’ve been connected to the internet and had the OLED say “No Internet Connection!”.

So for me, adding the power management options options 8732bu rtw_power_mgnt=0 rtw_enusbss=0 to /etc/modprobe.d/8732bu.conf appear to have helped resolve this issue. Although, I’ve just tested it a little at this point. Pretty fun to get the thing running for the first time!

Dear all, I am facing the very similar issue with the exact same behaviour observed by others on this post.

I tried most of the things mentioned here but issue is still unresolved. Kindly update if anyone could resolve this. I am going to try few things from power management side, will update here if it is resolved. Thanks!
